Abstract

A digitally based noise reduction filter was developed to reduce the noise associated with a purged dip-tube density measurement. An experimental density probe and measurement system was constructed to observe the measurement process and develop the corresponding filter design. The resulting filter provides adequate noise attenuation while passing the desired density information. Filter implementation utilizes existing measurement system capacity without the addition of extra signal-conditioning hardware.
